/**
 * @brief JIT-compatible wrappers for MayaFlux API functions.
 *
 * LLVM < 21 limitation: In-place lambdas cause infinite recursion during symbol resolution.
 * Workaround: All global MayaFlux API functions that expect std::function have template
 * wrappers here that accept callables directly. Use these in JIT code.
 *
 * Example (JIT):
 *   schedule_metro(0.5, [](){ std::cout << "tick"; }, "my_metro");  // ✓ Works
 *
 * Once LLVM 21+ is standard, in-place lambdas will work directly without these wrappers.
 *
 * @note This header is automatically included in the PCH for JIT contexts (MAYASIMPLE mode).
